From the National Weather Service:
Ready for yet another "bad hair day?"
Another warm and very humid day is ahead Wednesday, along with showers and thunderstorms, especially from Wednesday afternoon into Thursday morning.
Some of the showers and storms will be capable of producing localized flash flooding of urban areas (underpasses and roads) and possibly smaller rivers and streams. Something to keep in mind when out on the roads! In addition, thunderstorms may produce strong winds, which could bring down large branches or weakened trees.
Check out Wednesday's forecast highs and the latest rainfall forecast below.
When will the humidity break? Probably not before the weekend, after a cold front crosses the region Saturday morning.
